not able to access syslog server from ASA inside interface

suruchigupta555 — Fri, 04 Oct 2024 10:05:00 GMT

I am trying to access my syslog server over site to site vpn via ASA inside interface, it is not reachable. I'm not able to ping it as well from inside to Syslog. however, my remote users are able access the syslog via site to site tunnel successfully. this syslog server is in my internal network, but in different subnet.

I have checked from vpn configuration side, it's configured correctly. can someone please confirm if it is due to any known bug?

what is the syslog Server IP - from what source you trying to reach syslog Server.

Open ASDM Live Logs, and Intiate the Ping from source IP to Syslog Server see you can see the logs ?

is this traffic inside network traverse via Firewall ?

If this is Different VLAN, may be different Device doing that routing for you, not the Firewall i am in Guess.

basic checks :

1. are you able to ping syslog server

2. do the traceroute where the path leading to.

3. check any ACL on the VLAN SVI (if not going via Firewall).

You can do the same testing from syslog server to end device.
